I have a 2005 20' stratos with a tandem axle trailer.
This weekend when launching for a tournament my trailer brakes locked up when I went to put the truck in reverse. The trailer is supposed to have a bypass solenoid that will release when you put it in reverse. I have never had a problem until this weekend. I went back and pushed the manual release lever and it didnt help. had to put the truck in low 4 wheel drive and just make it slide the tires so I could get out of everyones way. I need help cause Im not sure where to start.
